RING-HOLDER FOR SPINNING AND TWISTING RINGS.

To all whom, it may concern:

Be it known that I, GEORGE L. PIERCE, a citizen of the United States, residing at Manchester, in the county of Hillsboro and State of New Hampshire, have invented an Improvement in Ring-Holders for Spinning and Twisting Rings, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention has for its object the production of a novel ring-holding means whereby a ring of one size may be readily substituted. for a ring of another size, according to the count of the yarn to be spun or twisted.

A ring-holding means comprising my invention includes a rail-plate and a detachable ring sustaining or receiving device that sustains the ring about which the traveler or yarn-controller revolves. Each sustaining or receiving device is provided with a ring of p the desired size, according to the count of yarn to be spun or twisted.

The rail-plate has a central opening of a size sufficient for the largest ring to be used and the bobbin to be filled, according to the diameter of the ring which is to be fitted thereinto.

The base of the ring sustaining or receiving device is of the same size and shape whatever the diameter of the ring, and it may fit in like manner the rail-plate, and said sustaining or receiving device is prevented from rotation on and is locked to the rail-plate and is thus prevented from being moved vertically and from being detached from the ring-plate except by overcoming the force of the means.

employed to effect the locking of the ring silistaining and receiving device to the ringate. p Figure 1 in side elevation represents a per tion of a ring-rail with my novel ring-holding means applied thereto. Fig. 2 is a plan view of Fig. 1 with the ring sustaining or receiving device or plate partially broken out. Fig. 3 is a section on the line 3, Fig. 2. Fig. 4 is a plan view of the rail-plate detached; and Fig. 5 is a plan view of the ring sustaining or receiving device or plate detached, the dotted lines therein showing different sizes of openings that may be made in the said device or plate for rings of different diameter.

Referring to the drawings, A represents part of a ring-rail, on which is shown as restmg about one of the usual spindle-openings therein a rail-plate a, shown as composed of Specification of Letters Patent.

sheet metal and provided with two lugs or uprights a a said plate having two like slots (i for the reception of the fastening-screws, that enter the ring-railand confine the railplate about the spindle-openings.

The central hole in the rail-plate is of a size sufficient to receive a mass of yarn of the greatest diameter, which is to be wound on the bobbin to be revolved in the usual opening in the ringrail. The lug or upright a acts as a positioning device for the ring sustaining or receiving plate I), to be GBSCrlbGd, while the lug or upright (1 forms part of a locking device, said lug orupright having, as

herein shown, a projection a which extends inwardly therefrom, said projection being shown as formed by a prick-punch.

The ring sustaining or receiving plate I), (shown detached in Fig. 5,) that receives the ring (1 or device that guides and controls the traveler d in its movement, is also represented as cut from sheet metal and is notched, as shown, at c to embrace the lug or upright a of the ring-plate to thereby position the ring d, of whatever diameter, centrally with relation to the spindle to be used. Said sustaining or receiving plate is provided opposite said notch with a lug 0, having, as shown, a recess, that may be formed by a prick-punch, to be entered by the projection a referred to, of the lug or upright a, said projection and recess constituting one form of locking means for preventing the lifting of the ring sustaining or receiving plate from the railplate except when the friction of said two parts is overcome, as it may be by inserting a piece of metal in the small opening 0 (See Fig. 1.)

The exterior contour of the ring sustaining or receiving plate may and is sup osed to be the same in shape for all sizes 0 rings; but the central hole (see Fig. 5) in said plate will vary in diameter in accordance with the di ameter of the ring to be sustained thereby.

The plate I) has, as shown, three upturned ears f, against which one of the flanges, herein the lower flange of the double ring, is engaged, said ring being forced into engagement with said ears, so that they hold the ring firmly.

It will be obvious that if a ring of smaller diameter is to be held in the plate I) a ring, for instance, the diameter of which corresponds to the dotted circular lines in Fig. 5, then the width of the plate I) from its exterior edge 6 to the inner edge 5 of the opening will IIO vary; but the ears in each different plate will be at the same distance from the inner edge 5. y

The ring sustaining or receiving plate has two open notches 2, in which rests the heads of the screws employed to fasten the rail-plate firmly to the ring-rail.

Believing that I am the first to mount a ring in a ring receiving or sustaining plate and thereafter apply said plate to the surface of a rail-plate permanently attached to aringrail and to lock the ring-receiving plate and the rail-plate together, I desire to cover this class of ring-holding means broadly irrespective of the particular construction shown, although the parts in which I have herein embodied my invention are the best known to me and are eminently practical.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A ring-holder comprising a rail-plate adapted to be confined to the top of a ring rail and having a positioning device and a locking device, and a ring sustaining or receiving plate having a notch, and a device coacting with the locking member of the raillate. P 2. A ring-holder comprising a rail-plate adapted to be confined to the top'of a ringrail and having a positioning device and a locking device, and a ring sustaining or re ceiving plate having a notch, and a device 00- acting with the locking member of the raillate, said ring sustaining or receiving plate aving ears combined with a ring forced into position between and held by said ears.

3. A sheet-metal rail-plate having one member of a positioning device and one member of a locking device, combined with a sheet-metal ring-receiver having a coacting ring-positioning device and a coacting locking device to operate substantially as described.

4. A sheet-metal rail-plate having two lugs or uprights, combined with a ring sustaining or receiving plate having a notch and an upright, the notch of the latter plate embracing one of the uprights of said rail-plate, the other upright of the rail-plate and the up right of the ring sustaining or receiving plate being adapted to engage one the othei frictionally to hold the ring sustaining or receiving plate seated operatively upon the railplate.

5. The combination with a ring-receiver having ears, of a double-raced ring forced into engagement with ears of said receiver, said receiver having a notch and also provided with one member of a locking device, and a rail-plate adapted to be secured to a ring-rail and having an upright that is engaged by the notch of the receiver, said railplate having a part forming thesecond member of a locking device.

6. In a ring-holder, a plate having ears to engage the flange of and hold a ring, and resilient means between which the plate may be inserted and snapped to confine the plate in working position. I

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE L. PIERCE.
